This vehicle has been off the road for 4-5 months. Ran fine before. Put a battery on it (not new but seems ok) Tried starting it and nothing. Used jump leads in case battery wasnt good enough to increase cranking speed if batter was lack lusture. Still no difference.
Hooked up lexia and got this fault p1671 Fuel pressure regulator short circuit to earth or open circuit. Tested connector and wire and it wasn't grounding. The pins on the pressure regulator was. Replaced part. Fault cleared with new part. Still doesnt start.
Disconnected fuel to HP pump and fuel is being pumped to it. Disconnect supply pipe to rail and nothing comes out the pump. Not sure if this is a fault of the pump or if the regulator wont let fuel through with rail disconnected.
Lexia shows 4 bars of fuel pressure measured when cranking which I know is miles of. Lexia desires 326.
Starts on easy start.
Leak off test shows no fuel leaking.. though I suspect nothing is getting to injectors.
High pressure pump 3rd piston deactivation actuator test works
HP fuel regulator actuator test works
Immobiliser shows as deactivated.
Stuck now. High pressure sensor on rail? what should cranking speed be?
